I recently heard this interpretation of targeting multiple creatures with spells that have "one creature/ level" as targets, and was wondering if this was legitimate:

"Example:

Cure Light Wounds, Mass; Caster Level 9
Target: One creature/level, no two of which can be more than 30 ft. apart
...cure 1d8 points of damage +1 point per caster level (maximum +25) in each selected creature.

In the above, each instance of 'creature' is actually a separate targeting of the spell, you do not have to select that many unique creatures as targets. For example, that 9th level character could target three creatures each three times, healing each one for 3d8+25 damage (1d8+9 times three, maximum +25)."

Is it intended by the wording of the spell to allow the same creature to be targeted more than once? Can this also occur for attack spells? (slow is a bad example because it's effects don't stack, but could it cause multiple saves if I targeted one creature more than once?)
